Be it known that 1,Joseeu ll. ROCKWELL,

tion of the clamping member.

end view of the clamping member, showing a citizen of the United States, residing at the city of Providence, in the munty of Providence and State of Rhodc" island, have mvented certain new and useful Improvements in Violoncello-Snpporta, of which the ifollowing'ia a s )tCiiiCtltlOll, reference hcing I jhad therein to't' 1c accompanying drawings. 1 0' This Invention relates to means for adustohly retaining the end pin in a violonee'llo,' and; has for its purpose to provide a intent. The in is-elso arranged so that it army he rcadllvpushed into lhe instrunwut out of the war ii icn not in use.

In the ordinary device for holding the end pin the gripping or binding mint is outside or below the bodjrof the cel o, leaving that pejr'tionnfthe pin which projects up inside othelmdy loose and free to vihrate. and hen theinstrnment is being played upon the natural vibration of the same tends to ke and rattle this pin, to the great annoycef'of the player. striieti0n I'have entirely obviated this difli- I firmlv grip and support the pint:

"vibrate and rattle is"' the greatest,

effor it to'rhak'e or make a noise. with these and otherobj'ect-s in view the (if certain novel feat ures of a will be more fully described;- n

"'lhe'op positc cud oi this socket is enlarged at 4,"

around which enlarged portion is formed a roove .3, which groove is for the purpoieeof receiving the fastening wire or cord (3, h which the tailpiece 7 agnilwt the tension of the strings. Playintcrior of this socket is threaded for a portion of itslcngtll'nt H, and the innerciitl ol' 'th'c the pin. hcn forced therein.

lmd portion ltl threaded to correspond with a "similar portion at 8 in the soc "ct.

of its length to give the same flexibility and allow it to he closed or clamped aroundthe end pin 13 to hold the same rigidlv in position. At the outer end of this hod v portion is an enlarged head 14, provided with a Fig. 5 is an This socketmay' he made of metal; or other suitable material and has a body is rctained in position a The end of this mcmhcr at ll is also tapering to "knurled ring 15, formln'gu eonveni'ent'iheans by which to manipulate the saideinln'ping member. 1 1 v a 3 The end pin 13 is a long "a indie-shef adapted to move freely through re'elampiagf member when the latter is not set ,apxjqr; tightened. The innerend of thin-pin hizsh'n enlarged head at 16,: which head preventgthb pin'lrom fallin out through thevsaid chi ,mg member. his head, liOWQVQi",-ij8 em enough to be .assed freely through the so an 3, thereby al owing it to be taken not of the cello without removing the said socket The lowerend of that pose of enga 'ng the hour or the like upon name from slipping. 3 i i g At 18 is a small step in which 1800 trant y of the and pin and is for the purptm of preventing the said end 'hich the cc 0 may rest to tter hold the ,plil for the )urpose of shar )clllng the point,

pin from inadvertently falling or being i pushed into the inside of the instrument.

In 0 crating this device the socket is 1 forced into the end of the cello, its tapering shank securely holding the some in position I therein. The tailpiece may then be secured l by the usual means to this socket and the strings of the instrument set up. The sharpened point of the end pin is passed through the clamping member and the little retaining-pin 18 inserted therein. This clamping member may then be screwed into thesocket until its tapering portion comes in contact with thesimilar portion in the socket,wher eb the slotted body portion of the former is closed or clamped together to firmly grip the pin and hold it rigidly and sccure-l in any desired position. It will he note the the mint where this pin is gripped is up insic e of the cello-body,where the greatest vibration of the instrument occurs when being played. This is an essential feature, as it securely holds said pin against shaking or rattling, which objection is found to b clmractcristic in all of the de* I vices of thisc turactcr nowon the market. it i is quite frequentlydcsired to remove this end which often iecomes dulled iyconstant service, and heretofore It has always bceli nccessary to completely unstrmp the instrument andtakc the whole device out to aci complish this purpose; but by my structure it"is only necessary to unscrew the clamping member and the pin may be readily removed for repairs and replaced.

The, device is extremely simple, practical, and ambient.

. Having thus described my invention, what I claim as new,and desire to secure by Letters Patent, i

1'. "As'devica of the character described comprising a riiiloncello, an end pin on which aaidcello rests, a'n'ocket'set intothe end of thainstrument and means whereby said pin' is ped' and held at the inner end of said soc ct within the body of the instrument.

2. A device of the character described comprising a Violoncello, an end pin on which said cello rests, a socket permanently held in comprising the end of the instrument, means whereby said pin is 'ripped and held at the inner end of said soc et within the body of the instrument, and means whereby said pin may be removed lrom the instrument without removing said socket.
